The Battle of Poitiers was fought on 19 September 1356 between a French army commanded by King John II and an Anglo-Gascon force under Edward, the Black Prince, during the Hundred Years' War. It took place in western France, 5 miles (8 km) south of Poitiers, when approximately 14,000 to 16,000 French attacked a strong defensive position held by 6,000 Anglo-Gascons.
Gascony was a province of the southwestern Kingdom of France that succeeded the Duchy of Gascony (602–1453). From the 17th century until the French Revolution (1789–1799), it was part of the combined Province of Guyenne and Gascony. The region is vaguely defined, and the distinction between Guyenne and Gascony is unclear; by some they are seen to overlap, while others consider Gascony a part of Guyenne. Most definitions put Gascony east and south of Bordeaux.
Béarn is one of the traditional provinces of France, located in the Pyrenees mountains and in the plain at their feet, in Southwestern France. Along with the three Basque provinces of Soule, Lower Navarre and Labourd, the Principality of Bidache, as well as small parts of Gascony, it forms the current Pyrénées-Atlantiques department. The capitals of Béarn were successively Beneharnum, Morlaàs, Orthez and then Pau.
The Battle of Winchelsea or the Battle of Les Espagnols sur Mer was a naval battle that took place on 29 August 1350 as part of the Hundred Years' War between England and France. It was a victory for an English fleet of 50 ships, commanded by King Edward III, over a Castilian fleet of 47 larger vessels, commanded by Charles de la Cerda. Between 14 and 26 Castilian ships were captured, and several were sunk. Only two English vessels are known to have been sunk, but there was a significant loss of life.
The Battle of Nájera, also known as the Battle of Navarrete, was fought on 3 April 1367 to the northeast of Nájera, in the province of La Rioja, Castile. It was an episode of the first Castilian Civil War which confronted King Peter of Castile with his half-brother Count Henry of Trastámara who aspired to the throne; the war involved Castile in the Hundred Years' War. Castilian naval power, far superior to that of France or England, encouraged the two polities to take sides in the civil war, to gain control over the Castilian fleet.
The Battle of Blanchetaque was fought on 24 August 1346 between an English army under King Edward III and a French force commanded by Godemar du Fay. The battle was part of the Crécy campaign, which took place during the early stages of the Hundred Years' War. After landing in the Cotentin Peninsula on 12 July, the English army had burnt a path of destruction through some of the richest lands in France to within 20 miles (32 km) of Paris, sacking a number of towns on the way. The English then marched north, hoping to link up with an allied Flemish army which had invaded from Flanders. They were outmanoeuvred by the French king, Philip VI, who garrisoned all of the bridges and fords over the River Somme and followed the English with his own field army. The area had previously been stripped of food stocks by the French, and the English were essentially trapped.
The Battle of Lunalonge was fought in the summer of 1349 between a French force numbering approximately 1,500 men and an Anglo-Gascon force of some 500 men, during the first phase of the Hundred Years' War. The location of the battle is thought to have been modern Limalonges in Deux-Sèvres. The outnumbered Anglo-Gascons, commanded by Thomas Coke, gained the upper hand during the day, but had to withdraw on foot during the night because the French, under Jean de Lille, had captured their horses. The French lost approximately 300 killed and an unknown but large number captured, including their leader.
The Battle of Auberoche was fought on 21 October 1345 during the Gascon campaign of 1345 between an Anglo-Gascon force of 1,200 men under Henry, Earl of Derby, and a French army of 7,000 commanded by Louis of Poitiers. It was fought at the village of Auberoche near Périgueux in northern Aquitaine. At the time, Gascony was a territory of the English Crown and the "English" army included a large proportion of native Gascons. The battle resulted in a heavy defeat for the French, who suffered very high casualties, with their leaders killed or captured.
William II Sánchez, Duke of Gascony from circa 961 at least until 996, was the younger illegitimate son of duke Sancho IV and successor, around 961, of his childless elder brother, Duke Sancho V. He united the County of Bordeaux with the Gascony. Documents of his reign state that his grandfather came from Iberia, lending credence to "phantasmagorical" genealogies placing the origins of García II Sánchez across the Pyrenees. He died in 996 or 997 and was succeeded by his son, Bernard William.
The Duchy of Gascony or Duchy of Vasconia was a duchy located in present-day southwestern France and northeastern Spain, an area encompassing the modern region of Gascony. The Duchy of Gascony, then known as Wasconia, was originally a Frankish march formed to hold sway over the Basques. However, the duchy went through different periods, from its early years with its distinctively Basque element to the merger in personal union with the Duchy of Aquitaine to the later period as a dependency of the Plantagenet kings of England.
Blessed Pey Berland was the Archbishop of Bordeaux from 1430 until his abdication, during a pivotal time in the history of the city and of Gascony. During his tenure, the city of Bordeaux remained staunchly faithful to the King of England in the last phase of the Hundred Years' War, but the French took the city in 1451.
Gadifer Shorthose was the English mayor of Bordeaux from 1434 until 1451. He was a weak leader and the city passed out of English lordship and into France during his mayorship.
The Battle of Bergerac was fought between Anglo-Gascon and French forces at the town of Bergerac, Gascony, in August 1345 during the Hundred Years' War. In early 1345 Edward III of England decided to launch a major attack on the French from the north, while sending smaller forces to Brittany and Gascony, the latter being both economically important to the English war effort and the proximate cause of the war. The French focused on the threat to northern France, leaving comparatively small forces in the south-west.
The Gascon campaign of 1345 was conducted by Henry, Earl of Derby, as part of the Hundred Years' War. The whirlwind campaign took place between August and November 1345 in Gascony, an English-controlled territory in south-west France. Derby, commanding an Anglo-Gascon force, oversaw the first successful English land campaign of the war. He twice defeated large French armies in battle, taking many noble and knightly prisoners. They were ransomed by their captors, greatly enriching Derby and his soldiers in the process. Following this campaign, morale and prestige swung England's way in the border region between English-occupied Gascony and French-ruled territory, providing an influx of taxes and recruits for the English armies. As a result, France's ability to raise tax money and troops from the region was much reduced.
The siege of Aiguillon, an episode in the Hundred Years' War, began on 1 April 1346 when a French army commanded by John, Duke of Normandy, laid siege to the Gascon town of Aiguillon. The town was defended by an Anglo-Gascon army under Ralph, Earl of Stafford.
Lancaster's chevauchée of 1346 was a series of offensives directed by Henry, Earl of Lancaster, in southwestern France during autumn 1346, as a part of the Hundred Years' War.
The Black Prince's chevauchée of 1356 was a large-scale mounted raid by an Anglo-Gascon force under the command of Edward, the Black Prince, between 4 August and 2 October 1356 as a part of the Hundred Years' War. The war had broken out in 1337, but a truce and the ravages of the Black Death had restricted the extent of the fighting since 1347. In 1355 the French king, John II, determined to resume full-scale war. That autumn, while Edward III of England threatened northern France, his son, Edward of Woodstock, later known as the Black Prince, carried out a devastating mounted raid, or chevauchée: an Anglo-Gascon army marched from the English possession of Gascony 675 miles (1,086 km) to Narbonne and back. The French refused battle, despite suffering enormous economic damage.
The Black Prince's chevauchée, also known as the grande chevauchée, was a large-scale mounted raid carried out by an Anglo-Gascon force under the command of Edward, the Black Prince, between 5 October and 2 December 1355 as a part of the Hundred Years' War. John, Count of Armagnac, who commanded the local French forces, avoided battle, and there was little fighting during the campaign.
The Gascon campaign of 1450-1453 took place during the Hundred Years' War when the kingdom of France undertook a military campaign to invade and cede the Duchy of Gascony from the English. Following the decisive victory of the French at the battle of Castillion and after the fall of Bordeaux, the last English stronghold in Gascony, English control of Gascony was removed.
English offensives in 1345–1347, during the Hundred Years' War, resulted in repeated defeats of the French, the loss or devastation of much French territory and the capture by the English of the port of Calais. The war had broken out in 1337 and flared up in 1340 when the king of England, Edward III, laid claim to the French crown and campaigned in northern France. There was then a lull in the major hostilities, although much small-scale fighting continued.
